To graph, you need a series of stress and strain data points. Was there an experiment that you performed, or were supposed to perform?
Yielding occurs when the stress-strain relationship is no longer linear; a "permanent set" then often occurs.
The failure load is, of course, the load at which the sample breaks. It is often referred to as the ultimate stress.
I don't know what you nmean by "gauge length"
hey we performed experiment and lecturer mailed the results which doesnt have any series of results just one result. And gauge length is length of the specimen used.
